I was tired picking my disc up off the floor and didn't like any other designs I seen.

I got tired of tangled cables and trying to hold both prongs while reading the meter. After a few prototypes I came up with this. It also worked out that I don't have to remove the prongs to check the batteries on my four-wheeler or lawnmower.

I broke my ash tray cover in my 2000 Jeep Cherokee and did not want to pay $50 for another used cover. I was unable to find anything I wanted to pay for or print. I took my broken part and began reverse engineering it. Now that my version is functional I want to share it with other Jeep enthusiast trying to keep their Cherokees on the road.
